| Title |
Replication timing of 10-799 leukemic patient sample, replicate 1 |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Early-replicating DNA of 10-799 leukemic patient sample
|
| Organism |
Homo sapiens |
| Characteristics |
diagnosis: ALL (T), Pediatric
age (yrs): 4
gender: F
disease stage: New Diagnosis
karyotype: 46,XX,t(5;14)(q35;q11.2)[14]/46,XX[6]
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Replication timing data were obtained by hybridizing early and late replication intermediates to NimbleGen oligonucleotide arrays, as described in Hiratani et al [PLoS Biology (2008) 6: e245]. Briefly, replication intermediates are prepared from cells that are first pulse-labeled with BrdU and then sorted into early (1st half of S) and late (2nd half of S) stages of S-phase by flow cytometry, followed by anti-BrdU immunoprecipitation of the BrdU-substituted (nascent) replication intermediates that were synthesized either early or late during S-phase. Samples were labeled after unbiased amplification of recovered DNA by whole-genome amplification (WGA; Sigma, GenomePlex). Further details can be found in Hiratani et al [PLoS Biology (2008) 6: e245].

| Label |
Cy3
|
| Label protocol |
Standard NimbleGen protocol (www.nimblegen.com/products/lit/index.html). Briefly, randomly-amplified BrdU-immunoprecipitated DNA samples (1 ug each) were Cy3- or Cy5-labeled by Klenow reaction using end-labeled Cy3- or Cy5-random 9-mers.

| Hybridization protocol |
Standard NimbleGen protocol (www.nimblegen.com/products/lit/index.html). Briefly, Cy3 and Cy5 labeled DNA samples (34 ug each) were co-hybridized to Nimblegen CGH arrays containing one oligonucleotide probe every 2.5 kb across the human genome.
|
| Scan protocol |
NimbleGen MS200 microarray scanner (Roche NimbleGen, Inc.) and MS200 data collection software were used per NimbleGen's standard protocol (www.nimblegen.com/products/lit/index.html).

| Data processing |
NimbleScan software was used to obtain .pair raw data per manufacturer's instructions. Raw early/late data (i.e. from .pair files) from two independent biological replicates in which early and late replicating DNA were differentially labeled were loess-normalized to remove signal intensity-dependent bias, then scaled to a reference data set to have the same median absolute deviation (limma package, R/Bioconductor).The early/late ratios were used to generate a smoothed profile (i.e. processed data) using local polynomial smoothing (loess, 300-kb span) for each chromosome using the loess function in the statistical language R. Processed data sets can be graphically displayed (and are also downloadable) on our web site (http://www.replicationdomain.org). Further details can be found in Hiratani et al [PLoS Biology (2008) 6: e245].
